About
I'm an independent researcher and engineering student passionate about building intelligent systems that solve my daily problems. I love competitive programming for the mental challenge and deep learning because it tackles the toughest issues I face. When I'm not coding, you'll find me playing guitar or experimenting with new recipes in the kitchen.
If you’ve got any questions or just feel like chatting, send me an (Email) I’d love to hear from you.
Projects
See AllTunsiGPT: Transformer LLM Trained from Scratch
Trained a transformer-based language model from the ground up on Tunisian Arabic, gaining hands-on experience in data preprocessing, tokenization, and generative model training. Built and cleaned large multilingual datasets, improving data consistency and reducing noise. Achieved measurable improvements in generation quality on low-resource dialects through systematic evaluation and architecture refinement.
EEG Seizure Prediction with Transformers
Advanced deep learning system using GPT-style transformers for EEG signal generation and seizure prediction 30 seconds in advance. Achieved 94% recall and 90.91% validation accuracy through transfer learning.
Interview Assistant: Real-Time NLP Guidance System
Built an end-to-end NLP assistant that transforms live conversations into structured guidance through personalized RAG pipelines. Designed fast audio-to-text processing feeding structured reasoning layers, reducing response latency while ensuring privacy-aware local deployment. Mirrors text-to-query and recommendation workflows used in analytical decision-support tools.
